摘要： An engine includes: two cylinder rows so placed as to be aligned side by side; a turbocharger; and an intercooler shared by the two cylinder rows, and connected to the turbocharger. The intercooler has: a cool liquid flow path through which a cool liquid flows, and an intake air flow path through which intake air from the turbocharger flows. The cool liquid flow path has an inlet and outlet of the cool liquid on one side in a first direction along the flow of the cool liquid. The intake air flow path has an inlet of the intake air on one side in a second direction along the flow of the intake air, and an outlet of the intake air on another side.

摘要： A piston engine described allows identical cylinder heads rather than requiring mirror image left and right heads. The engine has front and rear sides, with engine block containing two opposing cylinder banks. Identical heads mounted on block, with overhead camshaft structures in each head. Crankshaft between banks has front and rear gears. At rear is reverse-rotation gear mechanism with internal and external gears. External gear engages crankshaft's rear gear. First chain connects reverse-rotation internal gear to first camshaft sprocket on one head at rear. Second chain connects crankshaft's front gear to second camshaft sprocket on other head at front. Allows driving overhead camshafts of identical heads rather than requiring left and right mirror image heads.

摘要： A system and method are provided for an internal combustion engine. An engine system, in one example, includes a cylinder liner positioned within an opening of a crankcase, including a surface biasing a landing surface of an undercut fillet of the crankcase, and including a cylinder opening and a seal arranged in a groove of the cylinder liner positioned axially above the undercut fillet. The engine system further includes a fluid gasket and a combustion gasket positioned between a cylinder head and the crankcase, the fluid gasket and the combustion gasket being decoupled from one another.

摘要： A radial engine-generator includes an electric power generator and a radial engine. The radial engine-generator can be a mobile and portable unit, and is employable as a primary or back-up source of electric power at data centers, manufacturing facilities, electric vehicle charging stations, medical facilities, telecommunications, and residential neighborhoods, among many other applications. The electric power generator and radial engine are coupled together. The radial engine includes, among other components, multiple cylinders, multiple cylinder heads, and multiple overhead camshaft assemblies. The overhead camshaft assemblies are located at the cylinder heads and each include one or more camshafts. The camshaft(s) receive rotational drive input from a crankshaft of the radial engine. In certain implementations, camshaft carrier assemblies can be provided to support components of the overhead camshaft assemblies.
